EMSL analyzes air samples for most analytes using GC-ECD, GC-FID, GC-NPD, HPLC, LC/MS and/or GC-MS. The analysis and reporting of the individual sample is part of an overall process that includes analysis of quality control samples and programs such as Instrument QC controls, calibration standard checks, spiked media and reporting limit controls to ensure the confidence limits of the data are within the acceptable range as specified by the method requirements and our Quality Control Program.
EMSL's Industrial Hygiene Laboratories maintain normal business day operational hours with weekend scheduling availability as needed for critical response situations. Samples are received during regular business hours and Turn-Around Times (TATs) are tracked on business days. Lab turnaround times are offered for same-day or next-day, as well as for 2-day, 3-day, 4-day, 1-week and 2-week Standard TATs. Costs/rates are weighted based on the requested TATs with our 2-week TAT rates being the most cost effective for our customers.
Sample control/processing (log-in, results data-entry, reporting) is facilitated by our computer Laboratory Information Management System (LIMS) which tracks the sample job (batch) and provides the lab with work log (due dates) to help ensure all the work is organized and processed in accordance with the client's needs. Additionally, the LIMS includes security controls to ensure that information is controlled (locked) once the data is been documented and entered by the Bench Chemists. Reports can be delivered in a variety of formats at the customer's choosing, including email, hard-copy or both. Additionally, EMSL can provide Electronic Data Deliverables (EDD), as well as various QC Data Packages if required. Key tests include (but not limited to) the following:
